An Analysis on the Thermal Expansion Displacement of Concrete Bridge by 3D Laser Scanning Technology

Bridges are one of the most critical transportation structures related to a country’s national life, and usually main arteries of national economic development. In the past, the bridge construction only pursues the speed, along with the time passage, the bridge collapse accident often can causes the human life casualties. The concrete bridge materials behavior and the thermal expansion can cause the deformation. Therefore, in this paper, as temperature differences, analysis of the concrete bridge deformation by the 3D laser scanning Technology.
